One of the hydrolytic enzymes that catalyzes the hydrolysis of 5' -nucleotides into ribonucleosides and phosphate is the 5'nucleotidase, which is found in several organs. Oxidative stress shows depletion of antioxidants, such as glutathione (GSH), and the increased concentration of product of lipid peroxidation, such as MDA. The study comprised a total of 54 subjects including patients with beta thalassemia (n=27) and healthy volunteers (n=27) matched by age and gender. Hematology (Hb and % PCV), 5'-nucleotidase, Ferritin, GSH and MDA were measured using different methods and devices. The 5'nucleotidase, Ferritin, and MDA levels were significantly increased (p<0.001) in beta-thalassemia patients compared to the controls. As opposed to that, the Hb, % PCV and GSH levels were significantly decreased (p<0.001) in patients with beta-thalassemia. There was a negative significant correlation (r = -0.146, -0.245, p<0.05) between Hb and 5'- NT enzyme and PCV% with 5'- NT enzyme, respectively. While Hb had a high significant correlation (r = 0.956, p<0.05) with PCV%. In addition, 5'- NT enzyme had a positive significant correlation with GSH, MDA and Ferritin (r = 0.584, 0.442, 0.735, p<0.05), respectively. The present findings indicated an increase in the level of effectiveness of the 5'nucleotidase enzyme, ferritin and GSH in β thalassemia patients while decreasing in MDA

Despite the widespread utilization of Zinc Oxide nanoparticles (ZnO NPs) in different areas, there have been several studies regarding their toxicity. Thus, this study aimed to produce zinc oxide nanoparticles using a simple and eco-friendly biosynthesis process, utilizing the Eucalyptus (Eucalyptus camaldulensis Dehn.) as a reducing agent. It also aimed to estimate their insecticidal efficacies toward the mealworm's stages (Tenebrio molitor L.,1758(. The produced ZnO nanoparticles were characterized by X-ray diffraction, UV–visible, and transmission electron microscopy (TEM). The laboratory experiment was carried out with one way of exposure, using the feeding method through immersing the leaf in ZnO NPs solution with different concentrations. The mortality effects on insect's stages were recorded in various periods of time. The statistical analysis results indicated the presence of noteworthy variations in the average mortality rate according to insect's stage, showing a different effect on the average of larval mortality rate. In this regard, the highest average of larval mortality rate was recorded at 5000ppm (61.25%); while the general average percentage of adult emergence was (42.53%). After three weeks, the highest general mean of adult mortality was obtained at 5000ppm (87.48%). Similarly, the LC50 value of the ZnO NPs derived from the used plant extract against the larval stage was (3630.78 ppm). This result revealed that Zinc Oxide Nanoparticles from plant extract sources have both larvicidal and adulticidal properties and they could serve as an eco-friendly alternative to synthetic insecticides for controlling insect's stages. Hence, the biogenic Zinc Oxide Nanoparticles can be used as a potential bio-insecticidal agent for the future.

Polycystic Ovarian Syndrome (PCOS) is one of the most frequent gynecological endocrinopathy that occurs in premenopausal females. This study aimed to investigate the relationship between PCOS and Renin Angiotensin Aldosteron system, by measuring the levels of renin, ACE, Kallikren5, FSH and LH in follicular and luteal phase, in addition to evaluating the level of kallikrein 5, which belongs to the kallikrein-kinin system associated with the renin system. The renin-angiotensin system (RAS) is well known as regulator of electrolytes and blood pressure. Renin is previously considered a major enzyme in this system. The study included 90 blood samples for married women of childbearing age between (18-45) years. These samples included 70 samples for women with polycystic ovary syndrome, which were divided into two groups (35 samples in each one), the first was withdrawn in the follicular phase, named PA, and the second in the luteal phase of the menstrual cycle named PB. As for the remaining 20 samples, they represented the control group of healthy women, which were also divided into two groups (CA and CB) as happened with the patient group. In this study, the levels of serum Renin, ACE, LH, FSH and Kallikren5 were evaluated in PCOS patients and compared with the control group in both phases. The results were analyzed by T-Test and ROC. There were no significant differences between patients and the control group in terms of ACE activity or FSH (P>0.05). The results demonstrated that LH, Renin, and Kallikren5 were higher in patient group in both phases (P<0.05). Renin Angiotensin system was affected by PCOS.

This study investigated the conversion of 3,4-dimethylbenzaldehyde and 3,4-dimethoxybenzaldehyde into the corresponding oximes. In this regard, the condensation reaction between N-(3,4-dimethoxybenzyl) hydroxylamine with glyoxalic acid was accomplished to obtain the desired carboxylic nitrone. The FT-IR, 1H-NMR, and 13C-NMR spectroscopic techniques were used to identify the structure of the produced compound. Finally, the antimicrobial efficacy was assessed in terms of its action against the bacteria (Escherichia coli) as Gram-negative bacteria, (Staphylococcus aureus) as Gram-positive bacteria and fungus (Candida albicans). In conclusion, the activity data proved that this nitrone showed a significant antimicrobial activity compared to the standard drugs.

Wind energy is one of the main sources of renewable energy in the market today. The influence of the wind speed and the angle of attack on the aerodynamic noise was investigated in this study. Four different samples of airfoils were used. Three speeds (5, 10, 15 m/s) were employed. The results revealed that the aerodynamic noise was associated directly with the flow speed. The data showed that when the velocity increases by (5 m/s), the noise gets louder by an average amount of (10 dB). As the increase of flow velocity increased the velocity shear, this eventually increased the aerodynamic noise. As for the angle of attack, it had an effect on the aerodynamic noise as well. The results showed an increase in the overall sound pressure level between (1-4 dBA) when the angle of attack increased from (5 degrees) to (10 degrees), while there was an increase (1-6 dBA) when the angle of attack increased from (10 degrees) to (15 degrees). This study was conducted under subsonic flow condition and Reynolds number (3.3×104).

of titanium dioxide (TiO2) with several copper ratios were deposited on glass substrates using pulsed laser deposition (PLD) for pure and doped samples (TiO2 Pure, 1 % Cu, 2 % Cu, and 3 % Cu), energy (600 mJ), and frequency (6 Hz). X-ray diffraction (XRD) showed that the width of the peaks decreases with increasing the ratio of doping with copper. This leads to an increase in the crystal size and in the intensity of the copper peaks, as well as a gradual decrease in the intensity of the titanium dioxide peaks. The results of the atomic force microscope showed that increasing the inoculation percentage leads to an increase in the surface roughness and the average grain diameter, and thus an increase in the growth of the particle size. The electrical tests (Hall effect) showed that the prepared films are of (n-type) and that the concentration of carriers (n) increased with the doping ratio, while the mobility values (µH) decreased directly with the increase in copper. The electrical conductivity (DC) test showed an increase in the activation energy as a result of the increase in the copper inoculation percentage and thus the electrical conductivity increases.

ABSTRACT

In this study, the interacting Boson Model (IBM-1) was used to find the best Hamiltonian structure for studying the (_42^96,98)Mo structure. For generating the Hamiltonian structure, the calculated energy levels (ground, beta, and gamma bands) and B(E2) transitions for (_42^96,98)Mo were explored using the optimal parameter values. According to this study and the IBM test findings, (_42^96,98)Mo are stable isotopes of Molybdenum, and their transition behaviors are close to the SU(5) limitations. When comparing the findings to the experimental data, they demonstrated a good agreement.

In this work, thermal evaporation in vacuum technique was used to prepare the ZnO thin films as pure and doped with SnO2 NPs on glass substrates. The XRD pattern showed the hexagonal structure of ZnO with (002) preferred orientation. The EDX technique was used to investigate the contents of the film elements prepared which consisted of Zn, Sn and O. The concentration of Zn, O and Sn in the nanostructure films was different for all doping ratios. Thickness and morphology surface of the films were calculated from cross section of the surface films (~144 nm) using scanning electron microscopy images. The FE-SEM images confirmed the ZnO nanostructures and modifications of the morphology when adding SnO2. The pure film deposited was dense and structured; while ZnO: SnO2 (1,5 % wt) was a nanostructure. The optical band gap and Transmittance increased with the increase in the doping ratio of SnO2, while the absorption spectrum decreased for the prepared thin films. The prepared films showed different responses to the gas sensing at two different operating temperatures (100, 200 ºC) and the doping ratio increased the sensor value of the gas at an optimum temperature of (200 ºC).

A solution composed of calcium fluoride (CaF2) and methanol was precipitated using the chemical precipitation method for three samples in equal proportions. The samples were measured with X-ray diffraction with exposure times of (10, 15, and 20 sec). The peaks are displaced from each other towards the lower diffraction angles. This is attributed to the expansion of the crystal lattice due to the increase in the formation of atomic voids in the crystal structure of CaF2. Using a UV-Vis device, the absorbance of CaF2 suspended in methanol was measured and the energy gap was calculated, recording (3.7 eV) for direct transmission and (2.9 and 3.1 eV) for indirect transmission, resulting from crystalline defects. This represented another evidence of the presence of atomic voids in the crystal structure of CaF2, as the energy gap of CaF2 was (12.1 eV). The emission spectrum was taken at a wavelength of (300 nm) for the two samples with an exposure time of (10 and 20 sec) to X-rays, and (400 nm) for the sample with an exposure time of (15 sec). A shift was observed at the emission peaks, which confirmed a change in the intensity and displacement atomic voids.

The study area is located on the Dibdibba plateau in the middle of Iraq, particularly between the governorates of Karbala and Najaf. Given that the Dibdibba hydrogeological aquifer is thought to be the main source of water in this region, this site is chosen for performing the hydrogeological assessment. The study included 60 wells located on the west of the study area in Najaf Governorate. In these wells, the groundwater depths were measured in the field at the beginning of December 2021. The water stream was between 7.8 and 37.7 meters above the sea level, while the well depths ranged from 2.83 to 34 meters. Then, the spatial distribution of depths and water streams was mapped. Many wells were left by farmers because the water stream had gone down and the depth of the water had increased. The flow net of groundwater was determined to have two directions. The first direction was from the west to the east, and the second one was from the west and northwest to the southeast. The hydraulic properties of the Dibdibba aquifer in this study area were extracted by pumping tests. The experiments were carried out for five wells distributed over the area. The data was replaced with input into software for pumping tests, then analyzed by Newman's and Jacob's corrected methods for unconfined aquifers. Transmissivity values in experiments (T) ranged between 348 and 596 square meters/day, while hydraulic conductivity ranged between 14.1-22.5 m/day. The specific yield (Sy) equivalent to the storage coefficient in a confined aquifer was between 0.006 and 0.0302. The results of pumping test showed that the aquifer was of unconfined type according to the Neuman's and Jacob's corrected curves. In addition, the hydraulic property values were similar in all experiments with a slight difference, which may be related to the differences in saturated thickness, total depths, hydraulic gradient, and properties of rocks and sediments.

Reservoir characterization of the upper part of Qamchuqa Formation at the wells of Miran West-2 (MW-2) and Bazian-1 (BN-1) is studied. This formation typically has low shale content at the BN-1 well. At the same time, in the MW-2 well, the middle part of the studied formation is dominated by shaly and shale intervals, possibly affected by the Sarmord and Balambo depositional environments. Although the upper part of Qamchuqa Formation is mainly composed of dolomite with minor dolomitic limestone, marl and shale are occasionally present. Furthermore, porosity values are commonly less than 15% in both wells; nevertheless, there are a few intervals where porosity significantly increases. The formation at the BN-1 well has a higher porosity than the MW-2 well. Moreover, the secondary porosity is relatively low as 4.0% at the MW-2 well, while in the well of BN-1, it ranges between < 4.0% and 7.5%. The measured permeability of the formation suggests good permeability. According to the shale volume, porosity, and permeability, the upper part of Qamchuqa Formation is subdivided into three reservoir units. RU 1 at the MW-2 well and RU 2 at the BN-1 well have the most substantial reservoir properties. However, the lowest reservoir quality appears within RU 1 of the BN-1 well and RU 2 at the well of MW-2. Additionally, residual hydrocarbons constitute an extensive fraction of the pore spaces, while tiny portions of the moveable one can be discovered along all reservoir units of the formation. Finally, considering the hydrocarbon movability of the MW-2 well, the upper part of Qamchuqa Formation is defined by primarily movable oils in RU 1 and 2. In contrast, moveable oils are detected in almost all of the reservoir units of the BN-1 well.

The Iraqi government planned to complete the building of partially constructed Badush dam to protect against the collapse of Mosul Dam on Tigris River northwest of Mosul. The study aimed to derive the ge‎ometric parameters that compatible with the levels ranged 226.5-312 m (a.s.l.) such as reservoir volume, reservoir area, reservoir submerged area, perimeter, and average depth of the water column, which values ranges are 68039-12354976139 m3, 130074-407943574 m2, 130078-410538707 m2, 2.32-594.27 km, and 0.52-30.29 m respectively. These parameters were analyzed against the raising of the level, the spatial analysis of the geometric criteria and its relations with the levels of Badush reservoir showed that the relations between the volume of the positive bodies (islands), the undulated areas above water level which indicate the islands, and the planer areas (projections) of the islands with the level, fluctuates between increase and decrease with an increase in the level, as for the volume of reservoir, the submerged undulated area, the exposed planer area of the water pond, and the average water column depth they increased with the level increasing, unlike the thickness of the islands with the level, which fluctuates in increase and decrease with the level, the geometric analysis of the reservoir showed that Badush Dam is able to absorb the flood wave resulting from the collapse of Mosul Dam, at a level much lower than the level suggested in the preliminary studies that were adopted in the designs, because a large part of the water of Mosul Dam reservoir will remain in the same reservoir when the level is balanced after the collapse. between the two reservoirs, and that the results of this analysis represent a database that will be used in subsequent modifications in the designs.

The previous studies documented the tectonics setting, petrology, and geochemistry of the Penjween area (with Shalair Valley) before 70 years and considered it as an area of igneous rocks, and tectonically composed of three thrust sheets. According to these studies, the area includes two main igneous rock units: The Penjween Ophiolite Complex comprised of gabbro, peridotite, and granitoid intrusions at the south. The second unit is Kata Rash Volcanic rocks (Kata Rash conglomerate of the present study) which are located in the north and northeast and comprised of mafic, intermediate and felsic volcanic rocks. The present study disagrees with the previous documentation of these rocks and changed the claimed Kata Rash Volcanic Rocks and Penjween Ophiolite to metamorphosed conglomerates and coarse sandstones of the proximal facies that belong to metamorphosed sediments of Walash Formation (or Group) that was deposited in a large Paleocene Foreland Basin. The Walash Group and Kolosh Formation (as unmetamorphosed, coarse and fine sandstones or greywackes) were deposited as deep basin distal facies in the basin while Kata Rash Conglomerate belongs to coastal facies. All the above five units are deposited by turbidity currents during Paleocene-Eocene and they correlated, in the present study, stratigraphically along the basin paleodip from the present location of the Shalair valley to the south of Sulaymaniyah City. The Naopurdan Formation is recognized for the first time in the Penjween area and its facies and foraminifera are documented and correlated with Sinjar Formation. The above siliciclastic sediments were derived from volcanic source areas inside Iran and depending on the field, lab, and evaluations of the previous studies, the present study drew sedimentary stratigraphic columns and cross-sections for the Penjween and Sulaimanyiah areas and correlated their units along 100 km across the latter two areas. The correlation linked the Kolosh Formation with stratigraphic units of the Penjween area for the first-time supposing deposition during Paleocene-Eocene and sharing the same foreland basin which is aided by the first record of the occurrence of the Kolosh Formation in Chwarta by nannofossils and petrography.

This study focuses on the stability and catastrophic behavior of finite periodic solutions in non-linear differential equations. The occurrence of folding surfaces and their relationship with saddle-node bifurcations are explored, being classified as fold and butterfly types of catastrophes. Additionally, the application of catastrophe theory is discussed to analyze the qualitative changes in solutions with the change in system parameters.

The purpose of this study is to introduce the concept of homeomorphism via βm – closed set and study its behavior and properties in double fuzzy topological spaces. This objective is achieved through the definitions of df- βm continuous functions and df- βm closed functions. The results of this study represent important relationships and proofs, in addition to providing some necessary examples

this space when excluded from it, when the number of the components of that space increases. Therefore, this study aims at finding the necessary condition for fixed points in the inverse limit space to be cut points. Then, for applying the main theorem with some conditions, a sequence of upper semi continuous can be employed as a bonding function to get a union of continua as a generalized inverse limit space if there is a generalized inverse limit for each of them separately

In recent years, 3-term conjugate gradient algorithms (TT-CG) have sparked interest for large scale unconstrained optimization algorithms due to appealing practical factors, such as simple computation, low memory requirement, better sufficient descent property, and strong global convergence property. In this study, minor changes were made to the BRB-CG method used for addressing the optimization algorithms discussed. Then, a new 3-term BRB-CG (MTTBRB) was presented. This new method solved large-scale unconstrained optimization problems. Despite the fact that the BRB algorithm achieved global convergence by employing a modified strong Wolfe line search, in this new MTTBRB-CG method the researchers employed the classical strong Wolfe-Powell condition (SWPC). This study also attempted to quantify how much better 3-term efficiency is than 2-term efficiency. As a result, in the numerical analysis, the new modification was compared to an effective 2-term CG- method. The numerical analysis demonstrated the effectiveness of the proposed method in solving optimization problems

The process of detecting people in videos and then tracking their movement is one of the very important topics. The process of tracking people and studying their behaviour could result in a large set of information that can help researchers in studying reactions. The techniques of detection and tracking the movement of people are used in the sports field, where the athlete's movement is studied and analyzed within the game. Based on the information obtained from the process of tracking the athlete's movement, it is possible to improve the playing performance as well as avoid injuries and choose the best playing strategy. In some games, the accuracy of athlete's performance is a measure of the points given to the athlete's like gymnastics. This study reviews a set of articles that relied on computer vision as well as deep learning in the process of distinguishing and analysing the athlete's movement. The articles are confined to the years from 2015 to 2022, dealing with different indoor and outdoor sports. Certainly, the study of indoor games is better because the influence of weather conditions is less than that of outdoor ones. Reviewing the articles demonstrates that relying on computer vision systems is more effective than relying on human rulers, as humans are more prone to error. As for relying on the deep learning techniques for detecting the object, the results are very positive, due to the correct detection of the object. The results of the analysis of this object will be more accurate.
